  • How does one access subviews and handle groups of them?

    - by david
    If I want to manipulate a view I get it with [self viewWithTag:5];. Is there a better way to do this? Sometimes I need to manipulate a bunch of view (e.g. move them all out of the way. I do this by adding a UIView (e.g. UIView iHoldViews) and then adding the views, buttons, etc to this view. Then I can move the iHoldViews view and all its subviews move with it. Is there a better way to do this? (I have a feeling there is :) Maybe storing them in a NSArray or NSMutableDictionary ?

  • Completely Removing Views from memory

    - by cannyboy
    I have a view which is set up to train 'voiceprints' of words (this voiceprint code is not mine), and another view which has a slideshow which is controlled by the voiceprint. Unfortunately, these views conflict because they are still in memory. As far as I know, viewDidUnload and dealloc are only called in low-memory situations, and dealloc should not be called directly, so how do I completely remove a view. These views are within uinavigationcontrollers by the way.

  • Google Drive listing, searching and deleting files

    - by omarshammas
    I'm building a web app that integrates with Google Drive, and am wondering if there was a way to list, search or delete files. I see from https://developers.google.com/drive/v1/reference/files#resource that there are 4 operations. If there are no list and search capabilities then the onus is on the app to handle the management. Is there another API I should be using? Are those features in the works?

  • Getting screen height before first display?

    - by Mark
    Hi, I have a ListView. I populate it with 8 items, that's all that fits vertically on the G1. Some of my users are saying the Droid has a taller screen height, and so I can probably add one or two more items to the ListView to take up the additional space provided. How could I measure the available height the screen offers at startup, before the UI is displayed? If I see the height can fit more than 8 items, I'd like to add one or two more rows, Thanks

  • UIButtons display differently on UIImageView when created at design time vs. run time

    - by PRITISH
    I have added some UIButton objects into .xib file, and some UIButton objects with the code. But now I am facing one problem. While Zooming the UIImageView the UIButtons that are added through code are shown on the UIImageView and those that are added with .xib file are below the UIImageView. Code for UIButtons added with code: btnBrightness = UIButton.FromType (UIButtonType.RoundedRect); btnBrightness.Frame = new RectangleF (540, 20, 95, 37); btnBrightness.SetTitle ("Brightness", UIControlState.Normal); More details: monotouch

  • Having a problem with simple bool

    - by Code
    Hi guys, I've some really simple code that checks if my bool is == YES but it does not ever enter. NSLog(@"boool %d",self.arrayAlreadyPopulated ); if (self.arrayAlreadyPopulated == YES) { Match *aMatch = [appDelegate.matchScoresArray objectAtIndex:(numMatchCounter)]; aMatch.teamName1 = TeamNameHolder; } else { Match *aMatch = [[Match alloc] init]; aMatch.teamName1 = TeamNameHolder; [appDelegate.matchScoresArray addObject:aMatch]; [aMatch release]; } The debug at the top says that the value of self.arrayAlreadyPopulated is 1 on the 2nd pass as it should be. But it never enters the first first part but jumps down to the 'else' I cant see for the life of me what the problem is. -.- Anybody able to clue me in? Thanks -Code EDIT declaration code int theCounterCauseABoolWontWork; @property (nonatomic) int theCounterCauseABoolWontWork; @synthesize theCounterCauseABoolWontWork;

  • How do I use a default setting from Root.plist?

    - by crooksy88
    I have set up a default setting for my app using Root.plist, giving this a Boolean DefaultValue of YES (ticked checkbox).You can see a screengrab at http://www.infin8design.com/clients/stack/plist.png However, when my app is first launched, the YES value is not picked up, and the setting is read as a NO (or 0). The user has to manually go into the settings app, turn the toggleswitch off, then turn it back on again for this setting to hold a YES(1) value. I'm logging the value with appDidFinishLaunching like this. - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; NSLog(@"%d",[defaults boolForKey:@"include_phrases"]); SO... my question is... How do I pick up this initial default setting without the user having to set it manually? Thanks in advance for any suggestions you can offer. Mark

  • How to find out the format of a float?

    - by cannyboy
    I'm working with someone else's code, and there is a float with some unusual qualities. If I output the float using: NSLog(@"theFloat: %f", record.theFloat); I get: theFloat: 0.000000 However, if I use: NSLog(@"(int)theFloat = %i", (int) record.theFloat); I get: (int)theFloat: 71411232 How do I discover the real format and value of theFloat? I know that it should contain a large number. Incidentally, the Record class which contains the float propertizes it in such a way: @property (assign) float* theFloat; There is also floatLength: @property (assign) int floatLength; And has this method, which seems to indicate that the float is of variable length (?): - (void) copyFloat:(float*)theF ofLength:(int)len { float *floatcopy = malloc(len*sizeof(float)); memcpy(floatcopy, theF, len*sizeof(float)); self.theFloat = floatcopy; }

  • Convert "minutes since midnight" to time (convert to NSDate?)

    - by Canada Dev
    I am getting some open/closed times as integers since midnight. For example: "1140" = 19:00 (or 7 pm if you will) or; "570" = 9:30 (or 9.30 am) I can easily get the time in European format, just by doing doing a simple calculation and formatting: [NSString stringWithFormat:@"%d:00", (T / 60)] However, this doesn't work for half hours, such as "570 minutes since midnight". Also, I run into problems if I want to include a bit of localization, because some people may prefer AM/PM times. Does NSDate include a method for easily implementing times using the above? Or can anyone tell me how I would at least convert a time like "570 minutes since midnight" to 9:30 properly. Right now it obviously won't write the :30 part. Thank you

  • Adding images to an array memory issue

    - by Friendlydeveloper
    Hello all, I'm currently facing the following issue: My app dynamically creates images (320 x 480 pixels) and adds them to a NSMutableArray. I need those images inside that array in order to allow users to browse through them back and forth. I only need to keep the latest 5 images. So I wrote a method like below: - (void)addImageToArray:(UIImage*)theImage { if ([myMutableArray count] < 5) { [myMutableArray addObject:theImage]; } else { [myMutableArray removeObjectAtIndex:0]; [myMutableArray addObject:theImage]; } } This method basically does what it's supposed to do. However, in instruments I can see, that memory usage is permanently incrementing. At some point, even though I do not have any memory leaks, the app finally crashes. The way I see it, XCode does remove the image from my array, but does not release it. Is there a way I can make sure, that the object I want to remove from my array will also get released? Maybe my approach is completely wrong and I need to find a different way. Any help appreciated. Thanks in advance
